Bidirectional converters (BDCs) are important in electric vehicles (EVs). This study investigated different bidirectional power converters and their efficiencies, energy densities, and cost parameters. Control methods such as pulse width modulation (PWM) and hysteresis control are also examined. Comparisons on how well they regulate the output voltage and current in converters are performed. This paper also provides an overview of the types of BDCs used in EVs, including flyback, forward, and push-pull converters. The efficiency, energy density, and cost of each converter are assessed to identify the most appropriate model for EVs. The control methods including the advantages and disadvantages of PWM and hysteresis However, a shift to Continuous Conduction Modulation (CCM) is necessary to increase output power.

“…Concerning output current ripple, the converters in 30 , 31 are in ordinary parallel form, which holds no significance for reducing output current ripple, the converters in 28 , 29 and the proposed converter adopt interleaved parallel technology to reduce the output current ripple. Concerning current sharing method, in terms of current sharing method, the converter in 28 , 29 does not use the current sharing method, which will have a very negative impact on the life and heat dissipation of the converter. The converter in 31 adopts the active current sharing method.…”

This paper propose a wide gain single-bridge interleaved three-level LLC resonant converter with current sharing capability. This novel converter offers numerous advantages, including low cost, low current ripple, reduced voltage and current stress, widely gain range, high efficiency, good current sharing capability and versatile application scalability. Utilizing the three-level inverter + full-wave rectifier LLC converter as a representative case, the paper conducts an in-depth analysis and research on the proposed method. Finality, a 600 W experimental prototype was constructed and tested. Experimental results reveal that the proposed converter exhibits lower current ripple and a broader gain range. Moreover, the converter shows good current sharing capability (with a resonant element tolerance of 10%, the current error between the two phases does not exceed 12%) and high efficiency (peaking at 95.8%).
